srirc'xr'r ea'nou forrning part 'ofjLetters nTeitizenof the United States, residing at Philadelphia, in the county of ihihnlelphia andi'Stat'e of Pennsylvania, have invented a .hewand nsetnl 1m prove ment in Combined Gas, 1 Air, and Steam Rotary Engine, oi which the The uainreoi my invent'ion mainly consists 'in the introduction of gas, an and water sh .multaneonsly and together-into a tank canneeted with aeylinderot' as'tenm-engine, a. portion of the water being nsed'in iormingaj'aeket around the greater portion ofthe circumferenceof the cylinder, and niso to the ends thereof, and in the latter case acting as cushions to.

react against concussions, as hereinafter described. Another portionot' the, water is utilized in generating steam, which is -combined with the air and g'as'in their heated state for operating the engine. The means for inirm dncing the gas, air, and water into the engine and regulating the same, and also for beating them as theynrc passed intothe cylinder, are hereinafter fully described.

In the accompanying drawings, which make a. part. of this specification, Figure .1. is a vex.

Each jela'oi flame injected into the cylinder A frqrnth'c nozzle 19 of the pipe L ignites the gas nrl'l air it comes in contact with, whereby ins-in ,expa-nsive force is inerennerl ior the propulsion of the engine, and

also thereby, it rises into the tank l, and steam is generated in the space shove the waternnd descends through the pipe E into the cylinder A at cool: opening of the port 2, and coinbines with the gas curl air in propelling the engine. Each injection of a flame into the cylinder by suddenly striking the gas and air produces a concussion, and the numerous repented concussions thus produced, unless counteracted, are. cnlcniaieil to produce violentjars to the engine, which would much (is crease its spear and greatly derange it. I therefore make the chambers H H at the ends of the cylinder of sufficient capacity to form efficient cnshions'ro react; against the concussions, and thereby tend to produce an easy running of the engine, in addition to the use of said chambers as jackets for the ends of the cylinder A.
